Privacy

Analytics

ChemTable carries no advertising trackers and no third-party tracking pixels. When privacy-friendly analytics are enabled for a deployment they use Cloudflare Web Analytics, which is cookieless and does not fingerprint visitors or track you across other sites.

• No cookies are set for analytics.
• No cross-site or cross-device profile is built.
• Aggregate page metrics only — never your saved records or study answers.

Payments

ChemTable is free to use. If you choose to buy Premium, checkout is handled by RevenueCat (Web Billing) and Stripe. Your card details are entered directly into their secure checkout and never touch ChemTable's own code.

• An anonymous RevenueCat purchase id is stored in this browser (chemtable.rc.appUserId) so your Premium access is recognised on this device.
• Keep your receipt email — it is how you manage or recover access.
• Without a configured billing key the app ships fully free, with no purchase surfaces at all.

Everything stays in your browser

Your favorites, comparison selections, study notes, and view preferences are saved with your browser's localStorage. This study data never leaves your device and is not sent to any server.

• localStorage key: native-workspace:chem
• localStorage key: native-library:chem

You are in control of your data

You can export your saved state to a JSON file, or clear it entirely, from the Tools tab. Clearing your browser storage for this site removes all saved data permanently.

No accounts, no server database

ChemTable runs entirely as a static client-side web app with no accounts and no server database of your study data. The only data that leaves your device is what you export yourself, or the checkout details you enter directly with the payment processor if you buy Premium.
